Filed:

Jun 2, 1986

Appl. No.:

6/869524

Inventors:

John H. Goodacre - Glen Ellyn IL

Abstract:

The Removable Bottom Founded Structure (RBFS) is an offshore platform for petroleum drilling and producing operations intended for deployment in waters with severe weather and iceberg conditions. The structure is normally held down by gravity, but during the deballasting procedure a hold-down system is employed to keep the platform on the subbase until site evacuation. The system that is used to hold the platform down onto the subbase is located where the platform meets the subbase. It operates on the principle of hydrostatics. On the top surface of the subbase there are circularly arranged elastomeric bearing pads that define chambers which may be evacuated by pumping and which are vented to the outside atmosphere. Pressure by the platform on the bearing pads creates a fluid-tight seal so that no seawater will enter the evacuated chambers. The seawater evacuation causes a reduction of the buoyancy forces on the underside of the platform which will hold the platform onto the subbase until such time as the platform is totally deballasted.

Abstract:

Enamel insulation is stripped from a wire 1 by abrading the enamel coating with a pressurized stream of particles such as baking power, sodium bicarbonate. The particles chip off the relatively brittle coating, while the softer underlying wire is not harmed. The wire 1 passes through a chamber 4 and nozzles 18 direct the particle stream onto the wire 1. The chamber is evacuated at an outlet 34 to draw waste particles from the chamber 4. In another embodiment, the particle stream itself is directed through an outlet at the opposite side of the wire to entrain the waste particles and exhaust them from the chamber.
